Waya yebrown iri positive kana negative here?

18.02.2023 /

AC uye DC simba rekugovera bazi waya dzine mavara-coded kuti zvive nyore kusiyanisa pakati pewaya dzakasiyana. Muna 2006, UK wiring color designations yakawiriraniswa nemavara eruvara rwewaya muEurope yese kuti aenderane neInternational IEC 60446 standard. Nekuda kwekuchinja, waya yeblue yava waya isina kwayakarerekera uye girinhi/yellow pasi. , uye waya yebrown yakurukurwa muchinyorwa chino yava waya mhenyu. Zvino unogona kunge uchibvunza kuti, waya yebrown yakanaka here kana kuti haina kunaka?

Ramba uchiverenga kuti unzwisise zvirinani mashandisirwo nemashandiro ewaya yebrown (live) waya.

Brown waya: positive negative?

MuInternational Electrotechnical Commission (IEC) DC magetsi wiring color codes, waya yebrown, inonziwo live wire, iwaya yakanaka, yakanzi "L+". Basa rewaya yebrown kutakura magetsi kuenda kumudziyo. Kana waya yebrown iri mhenyu uye isina kubatana netambo yepasi kana isina kwayakarerekera, pane mukana unogona kubatwa nemagetsi. Naizvozvo, usati watanga kushanda pane wiring, ita shuwa kuti hapana sosi yemagetsi yakabatana newaya mhenyu.

Kunzwisisa Wiring Color Codes

Nekuda kwekuchinja kwemakodhi eruvara rwewaya, zvese zvakagadziriswa mains uye tambo dzemagetsi, uye chero tambo dzinochinjika, ikozvino dzine waya dzeruvara rumwe chete. MuUK mune misiyano pakati pekare uye itsva waya mavara.

Iyo yebhuruu isina kwayakarerekera wiring yakatsiva yakare nhema isina kwayakarerekera wiring. Zvakare, iyo yekare tsvuku mhenyu wiring yava shava. Matambo anofanirwa kucherechedzwa zvakakodzera newaya mavara macode akakodzera kana paine chero musanganiswa wemavara ekare uye matsva wiring kudzivirira kukanganisa kwechikamu uye kwazvakarerekera. Waya yebhuruu (yakarerekera) inotakura simba kure nechiridzwa, uye waya yebrown (inorarama) inopa simba kuchiridzwa. Uku kusanganiswa kwewaya kunozivikanwa sedunhu.

Iyo yegirini / yero (yevhu) waya inoshanda yakakosha kuchengetedza chinangwa. Kufambiswa kwemagetsi kwechinhu chero chipi zvacho kunogara kuchitevera nzira yepasi iyo inopa kushomeka kushoma. Iye zvino, sezvo magetsi achigona kupfuura nemuviri wemunhu munzira yepasi kana tambo mhenyu kana dzisina kwadzakarerekera dzakuvadzwa, izvi zvinogona kuwedzera njodzi yekuvhunduka kwemagetsi. Muchiitiko ichi, tambo yakasvibirira / yero yepasi inonyatso kudzika mudziyo, kudzivirira izvi kuti zvisaitike.

Chenjerera: Waya dzakagadzika uye tambo dzemavara akasiyana, pamwe nekumisikidza nemacheni, dzinofanirwa kunyorwa nezviratidzo zveyambiro. Iyi yambiro inofanirwa kunyorwa pafuse board, circuit breaker, switchboard kana mutengi unit.

IEC Power Circuit DC Wiring Color Codes 

Colour coding inoshandiswa muDC magetsi zvivakwa zvinoteerana ne AC miyero senge solar power uye computer data centers.

Zvikumbiro zvemuenzaniso

Kana uchangobva kutenga chigadziriso chemwenje uye uri kuyedza kuchiisa muUS, senge mwenje we LED wokupaka kana mwenje wemba yekuchengetera. Iyo luminaire inoshandisa pasirese wiring zviyero uye neiyi nzira, kuenzanisa iri nyore:

  • Waya yebrown kubva pamwenje wako kuenda kune nhema waya kubva muchivakwa chako.
  • Waya yebhuruu kubva pamwenje wako kuenda kuwaya chena kubva muchivakwa chako.
  • Yakasvibira ine tambo yeyero kubva pane yako kusvika kune waya yegirinhi yechivakwa chako.

Iwe uchanyanya kubatanidza dzimwe waya mhenyu kune tambo dzebrown nebhuruu dzechishandiso chako kana uchimhanya pa220 volts kana kupfuura. Nekudaro, ma voltages akakwira anofanirwa kushandiswa chete mumamiriro akanyanya. Zvizhinji zvemazuva ano zvigadziriso zve LED zvinoda chete 110 V, iyo yakakwana. Chikonzero chega cheizvi kana paine mitsetse mirefu, senge kumhanya 200 tsoka kana kupfuura dzewaya kunhandare dzemitambo dzakareruka, kana nzvimbo yacho yatobatana ne480 volts. (2)
